2. SnapSave
Simple UI but overloaded with ads and no subtitle support. Fine for an occasional quick download if you don’t mind closing pop-ups.
3. YTMP3.cc
One of the oldest sites—fast downloads but relentless ad redirects. Not recommended for regular use.
4. 9Convert
Clean layout, yet inconsistent speeds and no editing or subtitle tools.
5. Y2Mate
Popular, but recent malware and extension issues make it risky. Best avoided if you value your device’s security.
